Introduction: Maintenance of the exhaust aftertreatment system is important to ensure optimal performance and reduce emissions on your International EPA0710 Maxxforce 1113 engine. The exhaust aftertreatment system consists of components such as the Diesel Particulate Filter (DPF), Diesel Oxidation Catalyst (DOC) and Exhaust Aftertreatment Injectors (AFI). If any of these components are cleaned or replaced, you should reset the soot levels using the Exhaust Aftertreatment Reset procedure in the JPRO Diagnostic Software.
Supported Engines: The Exhaust Aftertreatment Reset procedure is supported on International EPA 07 and EPA 10 Maxxforce 11 and 13 engines. It is important to note that performing this procedure when none of the exhaust aftertreatment components have been cleaned or replaced may result in premature clogging of the system with ash and soot.
Step by step instructions:
1. In JPRO, select “Post Process Reset” and press Enter or Start to begin the process.
2. The Post Process Reset dialog box will appear on the screen.
3. For EPA 07 International engines, select the appropriate test from the selection box. Options include New DPF Installed, DPF Cleaned, New or Cleaned DOC, or New or Cleaned AFT Fuel Injectors. Note that test selection does not apply to EPA 10 or EPA 13 International engines.
4. Ensure all prerequisites are met and click the Reset button to begin the reset process. Follow the instructions on the screen Dialog box instructions.
5. Turn the ignition off and select the Next button (previously called the Reset button).
6. Wait for the displayed timer to expire. When the process is complete, the “Exit” button is enabled and displays the instruction “Turn ignition on to restore communication.”
7. Turn on the ignition and wait for communication to be restored.
8. When the status updates to “Operation completed successfully,” press “Exit” to return to the Test Selection dialog box.
Conclusion:
Resetting the exhaust aftertreatment system with JPRO is a simple process that should be performed after cleaning or replacing the DPF, DOC, or AFI components on your International EPA0710 Maxxforce 1113 engine. Following the step-by-step instructions will ensure that the reset is performed correctly and engine performance and emissions control capabilities are maintained. To avoid premature clogging and other problems with the exhaust aftertreatment system, resets should only be performed when necessary.
